Electroweak Physics [W/Z]
The production of a pair of high-transverse-momentum leptons plays a very important role at hadron colliders:
it allows the precise measurement of basic parameters of the Standard Model like the masses and decay widths of the W and Z bosons and the weak mixing angle; it provides stringent constraints on the parametrization of the proton parton density functions; it could provide a tool to...

We present the most precise single measurement of the W boson mass and and a measurement
of the W width using data collected with the D0 experiment. An integrated luminosity of
1 fb-1 yields 499,830 W->evcandidates. The mass is measured with an uncertainty of less than
45 MeV while the width uncertainty is less than 75 MeV.

Electroweak Physics [W/Z]
I will review experimental issues related to W and Z boson production at hadron
colliders, with particular emphasis on the measurement of the W boson mass.
Recent measurements of W and Z production from the Tevatron will be discussed,
as well as topics covered at the recent Milan workshop on the W mass measurement.

Electroweak Physics [W/Z]
At LHC, the production cross sections of the W/Z bosons are at tens to
hundreds nanobarns level. Studies of these processes can not only help the
detector commissioning, but also help to establish standard candles for
exploring beyond-the-SM physics, such as searches for Zprime, Wprime
particles. The leptonic decays of W/Z bosons are expected to have very high
trigger efficiency and...

One of the benchmark analyses to be performed with the first data at the CERN Large Hadron Collider will be the measurement of the Z boson transverse momentum spectrum. I will present a prospective analysis for this measurement in the dimuon channel on the ATLAS experiment. The analysis uses simulated datasets at a center-of-mass energy of 10 TeV. After summarizing the motivations for the...

Electroweak Physics [W/Z]
We present the strategy of the measurement of the differential cross-section
of Drell-Yan dimuon production in early proton-proton collision data
produced by the LHC accelerator at $\sqrt{s}=$~10~TeV and collected by the
CMS detector. We study the Drell-Yan dimuon process for the whole mass
range, starting around the $\Upsilon$ peaks, and going through the $Z$ peak
to the kinematic...

Electroweak Physics [W/Z]
The study of W or Z boson with accompanying hadronic jets in final states is of high importance at hadron colliders both to understand Standard Model processes and to measure background to Beyond Standard Model physics searches. The presence of one or more jets in the final state increases the complexity for the reconstruction of leptons and of missing transverse energy. The ATLAS prospects...
